IMPROVEMENT IN HOSE-COUPLING SPANNERS.

Specification forming part of Letters Patent No. 144,862, dated November25, 1873; application iiled October 31, 1873.

To all whom it may concern:

Be it known that I, LEwIs POND, of Foxborough, of the county of Norfolkand State of Massachusetts, have invented a new and useful Improvementin Hose-Coupling Spanners; and do hereby declare the same to be fullydescribed in the following specification and represented in theaccompanying drawings, of which- Figure 1 is a side elevation, and Fig.2 an edge view, of a Spanner as improved by me.

It consists, mainly, of two levers, A B, crossed on each other andpivoted together at the crossing, the shorter arms b b of the saidlevers being curved, as shown, (to fit to a coupling,) and provided withan eye or hole, a, in each to receive a stud from the coupling, and thelonger arms being hooked and bent, as represented.

. Instead of a hole, a, in each of the shorter arms, such arm may befurnished with a stud or projection to enter a corresponding hole in thecoupling, provided such coupling has holes instead of studs to operatewith a spanner. It will be observed that each of the larger arms is notonly bent so as to form a hook, e, at and near its end, but it is alsobent, as shown at d, in order that when the two arms are closed togetherthere may be a space or opening, f, between them for the insertion ofthe third finger of the hand of a person, when one hook hangs upon thesecond and the other on the fourth iinger of such hand. Y By the thirdiin ger going between the arms, a person, while supporting the Spanneron and by his second and fourth :lingers of his right hand, can use thethird finger to open the spanner preparatory to closing it upon acoupling; and, further more, he can exert his force to lift the hose byand drag it along with the spanner to better advantage with the threelingers so applied to the Spanner than he can with two only.

I therefore claim- The hose-coupling Spanner, constructed substantiallyas described and shown, viz., of two crossed levers, A B, pivotedtogether, and provided not only with hooks c c and eyes a a, disposed asexplained, but with the linger-opening f between the longer arms, all asset forth.

LEWIS POND.
